Figure 2.

Auditory association cortex activated in the group of nonhallucinators by both hearing and hallucinating conditions. Orthogonal projections of the region identified by the combination of four contrasts: the conjunction of two orthogonal contrasts (threshold, P = 0.001), hallucinate vs. baseline, and hearing vs. imagining, masked with two other orthogonal contrasts (threshold, P = 0.05), hearing vs. baseline, and hallucinate vs. imagining. The identified region lies in the right Brodmann area 22, and its maximum (z = 4.44, 73 k, P = 0.02 voxel level significance) is located at {52,-38,4} (16).
